الجواب 



Following two commands will ensure your purpose

 فيما يلي الاوامر التي تمكنك من تنفيذ طلبك 
chmod -R 755 /directory
chown -R owner.group /directory
This will give read permissions to everyone. You may be facing issue due to wrong ownership. If the file is not very sensitive, you can also use:


 والتالي سيعطي صلاحية القراءة للجميع. وهناك إمكانية مواجهة مشكلة وذلك بسبب خطأ في ملكية الملف


chown -R nobody.nobody /directory   ( No body means anyone )

How to take a screenshot on a Mac

hold down command ⌘ and shift and press 3 = Your Mac captures the entire screen and saves it as a file on the desktop. The file name will look like“Screen shot 2015-03-08 at 08.45.00 AM.png”.

How do I take a partial screenshot?

hold down command ⌘ and shift and press 4 = Use your mouse to draw a rectangle in order to specify what to capture – or press the spacebar and then click on something (e.g. awindow) to capture it. Your Mac then saves it as a file on the desktop. The file name will look like“Screen shot 2015-03-08 at 08.45.00 AM.png”.

I don’t need a file. How can I have a screenshot in the clipboard instead?

hold down control together with any of the combinations above = Your Mac takes a screenshot and copies it to the clipboard (instead of saving it as a file).

I guess it’s in the clipboard now. How can I paste it into a document or something?

hold down command ⌘ and press V = Your Mac pastes the screenshot (that is in the clipboard) into a document or image you are currently editing.
